The answer? Pizza boxes! And big bamboo steamer baskets, too.
Pizza boxes can be found at restaurant supply shops, and you can even ask your corner pizza shop if they'll let you have one or two empty boxes. (When you're down there anyway, buying your Wednesday-night-before-Thanksgiving pizza, of course!) They are usually about 2 inches tall, which is just tall enough for many (although not all) pies. But what they're really great for is transporting small appetizers and cookies. Little candies fit well, too.
We found the idea for using steamer baskets at Martha Stewart. Again, this uses a common and easily-found item (you may have one in your kitchen) and repurposes it for holiday usage.
Along with these two things, you can also transport pies in really any square box you have handy; just cushion it with some tea towels and carry carefully.
